A new method for characterizing particles triboelectrically charged through repeated contact with a wall has been studied both theoretically and experimentally. The condenser model was applied to formulate the particle charging. In the experiment, particles that were fed on a vibration plate could travel on the surface, and the charge on the particles was measured using a Faraday cup. Particle behavior on the oscillating plate was observed using a high-speed camera with a zoom lens. It was found that the profile of particle charge as a function of distance travelled on the vibrating plate or the number of particle-wall contacts agreed well with the theoretical one, which is determined by two parameters related to equilibrium and relaxation. It was also found that particle tribocharging is well-characterized by the values of the parameters obtained by external electric fields.

本文从理论和实验两方面研究了一种表征颗粒与壁面反复接触摩擦带电的新方法。采用电容器模型来描述粒子荷电过程。在实验中，在振动板上进料的颗粒可以在表面上行进，并且使用法拉第杯测量颗粒上的电荷。使用具有变焦透镜的高速照相机观察振动板上的颗粒行为。有人发现，作为振动板上的距离或颗粒壁接触的数量的函数的粒子电荷的轮廓同意与理论的，这是由两个参数有关的平衡和松弛。研究还发现，颗粒摩擦充电的特征在于由外部电场获得的参数的值。
